Seems like there is so much subjectivity in certain games that you're just better off not calling it, sadly.
Can't NOT make the call on a clear-cut penalty there just because of the name on the opposing team's jersey.
Now having said that, I wouldn't make a big stink about it if I am the Big XII Commish, as ASU still had their chances after that debacle.
Sure, if UT had ended the game in regulation on a made FG as time expired, then rant away.
But as it played out, ASU was still in prime position to win in OT if they just defend 4th and 13 properly.
Plus, even if the targeting penalty had been called, there was no guarantee ASU makes a game-winning FG themselves.
But to the original point, all parties need to re-evaluate what IS AND IS NOT targeting in the off-season.
